Howto UNinstall software RAID 1 without loosing data

Hello guys, this one is a bit tricky I hope someone can help, here it goes, I am trying to migrate a server from REDHAT to DEBIAN remotely, I have the procedure to do it and have tested it with success, however the server is running SOFTWARE RAID 1 and I need to uninstall the RAID 1 without loosing any data and be able to restart the server. so what I was planning to do is:

1. change the boot device in grub from /dev/md2 to /dev/hda2 (that is the boot partition)

2. edit /etc/fstab all entries from /dev/md* to /dev/hda*

now the part I have no idea on how to accomplish is:

1- stop the array and prevent it from loading the next boot.

2- remove the Linux Raid autodetect from the partitions without loosing data

Is out there anybody willing to help? please just reply only if you are sure, I can't afford to loose this server, is my first week at work.

Thanks in advance

Server running raidtools-1.00.2-1.2

I have some theories, but I won't patronize you - per your request. Time to make use of that Red Hat support contract. Important situations like this require a good outlet for finger pointing... er, I mean collaboration.
